STUMP-MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,957, dated February27, 1883.

l Applicationiled May 24, 18S-2. (No model.) I

To all whom it may concern:

Be it known that I, WTLLIAMH. HAMILTON, a citizen of the United States,residing at Watrousville, in the county of Tuscola and State ofMichigan, have invented certain new and useful Improvements inStump-Pullers; and I do hereby declare that the followingis a full,clear, and exact description of the same, reference being had to the,accompanying drawings and the letters of reference marked thereon, whichform a part of this specification, and in which- Figure lV is aperspective view of my improved stump-puller, and Fig. 2 is aperspective view of the lever detached.

The same letters refer to the' same parts in both gures.

This invention relates' tomachines for extracting stumps; and itconsists in certain improvements in the construction of the same,

which will be hereinafter more fully described,

and particularly pointed out in the claims.

In the drawings hereto annexed, A represents the body of my improvedmachine, which consists of two horizontal parallel planks, A2 A2, whichare spaced and connected by bolts or braces a ct. The said planks areprovided near their edges with two series of vertical pcrforatious, b b,so located that the perforations at one side shall register with or belo cated opposite the spaces between the perforations at the other side,as clearly shown in Fig. 1 of thedrawings. D D are pins or bolts fittedin the said perforations, as shown.

O is a plate secured between the planks A2 A2, at one end of themachine, by means of a holt and nut, (denoted by c.) Said plate has atits outer end an opening or perforation, d, to receive means forconnecting; it with a snitable anchoring device, by which the machinemay be made fast and held securely in position during operation.

The operating-lever B, which is shown detached in Fig. 2 of thedrawings, is provided in its outer side or edge with two recesses, rr,adapted to receive the pins or bolts D D when the said lever is placedin position between the planks A2 A2 of the machine.

S is a bail or staple secured to the side of the lever between therecesses rr. The outer end of the lever is provided with aspindle, Gr,upon which is journaled a wheel, F. H is a chain connected or secured tothe staple S of the lever.

In operation, the chain H is connected or made fast to the stump to beextracted. The lever'is then moved back in the machine as far aspossible, and the pins or bolts D D adjusted in their respective holes,the lever having been so placed that one ofthe bolts D shall fit in oneof the recesses r. Draft is then applied to the outer end of the lever,which, being supported upon the wheel F, will move easily and withoutdragging. The pins or bolts D are alternately shifted or moved back asthe lever in loosening the stump moves back in the frame.

My improved stump-puller is exceedingly simple in construction, durable,and it may be manufactured at a trilling cost.

I claim as my invention and desire to secure by Letters Patent of theUnited Statesl. In a stump-puller, the combination of the frame or bodyconsisting ot' two horizontal parallel planks, spaced and connected bybolts or braces, and provided at the edges with vertical perforations,those at one side being located opposite the spaces between ,those atthe other side, the anchoring block or plate O, the pins or bolts D D,and the lever B, having recesses r 1^ and staple S, substantially as andfor the'purpose set forth.

2. In a stump-puller, the combination, with the frame A, havingperforations b b, the anchoring-plateb, and pins or bolts D, oftheleverB, having recesses r r, staple S, chain Hkspindle G, and wheel F,substantially as and for the purpose set forth.
